ANCHOR Filed Jan. 15, 1954 v l GE JOE Patented Dec. 4, 1934 UNITED STATES PATENT OFFICE ANCHOR Application January 15, 1934, Serial No. 706,783

2 Claims.

This invention relates to improvements in anchors and has particular reference to an anchor which will not become fouled with the anchor chain.

A further object is to produce an anchor of this kind which will always be positioned correctly so that the fluke will bite into the ground and truly anchor the ship to which the same is attached.

A still further object is to produce a device which is simple in construction and therefore economical to manufacture.

In the accompanying drawing forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Fig. 1 is a perspective View of my anchor,

Fig.2 is a top plan view of Fig. 1 on an en.- larged scale,

Fig. 3 is an end elevation looking from the eye end, and

Fig. 4 is an enlarged cross sectional View on the line 4-4 of Fig. 2.

An ordinary anchor consists of a stock, a cross bar and a pair of fiukes together with means for attaching an anchor chain or cable thereto. Due to the fact that this type of anchor has two diverging flukes, one engaging the bottom surface and the other projecting upwardly into the water, it is obvious that a boat which is attached to the anchor by a slack chain and swinging around as the tide ebbs and flows, it is very liable to have its chain become entangled with the upstanding fluke and it may so happen that this entanglement may be sufficient to lift the anchor out of contact with the bottom under certain conditions of strain upon the anchor chain. This mightbe a serious matter, should the boat drift away, as has often occurred. Applicant has, therefore, devised a new type of anchor which overcomes these difliculties.

In the accompanying drawing, the numeral 5 designates the shank of the anchor and the numeral 6 the cross piece thereof. These features are common to all anchors. With my anchor I prefer to turn the ends '7 and 8, of the cross piece, downwardly, the purpose of which will be later seen. An eye 9 serves to connect the chain 11 to the shank 5. The numeral 12 designates a fluke extending from one side of the shank 5. This fluke is similar to the ordinary anchor fluke. Instead of providing a similar fluke, I have attached to the top side of the shank 5, a pair of plates joined together along their semicircular edges 13 so as to form an air space 14 therebetween. These plates are designated b the numerals 16 and 17.

The result of this construction is that when the anchor is thrown overboard, the portion formed betweenthe plates 16 and 17 forms an air tank of rudder formation. Consequently as the anchor descends, it will descend in substantially the position shown in Fig. 1, that is, with the fluke 12 extending downwardly and with the plates 16 and 1'7 extending upwardly. This will bring the cross piece 9 onto the ground with the ends 7 and 8 extending downwardly. Now if the ship should drift the anchor chain will naturally ride over the semi-circular edges 13 of the plates 16 and 17 and will not be entangled with a second useless fluke as would be the case with the ordinary anchor. Also by turning the ends 7 and 8 of the cross piece 6 downwardly, the chain will slide over the ends of the cross piece.

It is believed that this anchor will perform all the objects above set forth and be a much safer anchor to use.

Having thus claim:-

1. An anchor having a shank and a cross piece, a single fluke secured to said shank, a rudder arrangement secured to said shank and diametrically opposed to said fluke, said rudder including a pair of plates secured together at their edges to provide an air space therebetween.

2. In an anchor comprising, a shank, a cross piece secured to said shank, a fluke secured to said shank and extending in a plane at right angles thereto, the ends of said cross piece being turned downwardly in the direction of the plane occupied by said fluke, and an air chamber formed of a pair of spaced plates joined at their edges, secured to said shank and diametrically opposed to said fluke, said air chamber serving to act as a float and rudder for directing the downward travel of the anchor into contact with the surface to which it is to engage.
